• Ashely DiPadova, Dan Kelly

2
What Will Be Covered

• Kinetic Energy
• Kelvin Temperature
• How the Two Are Related
• The Kelvin Scale

3
Kinetic Energy

• Kinetic energy is the energy an object has
  because of its motion

4
Kelvin Temperature

• Kelvin Temperature, or absolute zero, is the
  temperature at which the motion of particles
  probably stops.

5
How the Two Are Related

• An increase in the average kinetic energy of
  particles causes the temperature of a substance
  to rise.
• As a substance cools, the particles move more
  slowly, and their average kinetic energy declines
• Particles would have no kinetic energy at
  absolute zero because they would have no motion

• The following graph shows the distribution of
  kinetic energies at two different temperatures

7
Continued

• The Kelvin temperature scale reflects the
  relationship between temperature and average
  kinetic energy.
• The Kelvin temperature of a substance is directly
  equal to the average kinetic energy of the
  particles of a substance.

Conclusion

• Kelvin temperature effects the kinetic energy of
  a substance
• If temperature increases, so does energy
• At any given temperature the particles of all
  substances, regardless of physical state, have
  the same kinetic energy.
